eral triangle is intended to alert the user
to the presence of important operating
and maintenance (servicing) instructions
in the literature accompanying the appli-
ance.

NOTE: This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide rea-
sonable protection against harmful interference when the
equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be
required to correct the interference at his own expense.
FCC Caution: To assure continued compliance, (example -
use only shielded interface cables when connecting to com-
puter or peripheral devices). Any changes or modifications
not expressly approved by the party responsible for compli-
ance could void the user’s authority to operate this equip-
ment.

■General
The CPU Switch Unit is designed to switch over the
redundant (Duplicate) CPU system, automatically or
manually for maintenance reasons. This unit will always
diagnose both CPUs condition and judge which CPU
must be active. Diagnostic tables and judgment logic
are designed with flexible architecture which makes it
possible to customize it, depending on the level of
security requested by the user.
If this unit decides on a CPU change over, it must first
deactivate the previous CPU, and wake up the standby
CPU to be active later. Therefore this unit has a CPU
reset function and can restart the CPU in the standby
mode. Also, this unit will indicate the target CPU to be
active or on standby. Even if this unit is defective or
powered off, it can transmit the mode indications (the
active mode or standby mode) to the CPU, because of
the relay parts which are used for the interface with the
CPU.
And this unit has a status display with LED indications,
so a maintenance engineer will easily understand the
CPU condition, which CPU is active, and etc.

iFuse Holder
oAC Inlet Socket (AC IN)
Plug the power cord (supplied as a standard acces-
sory) into this socket and connect it to an AC outlet.
■Mounting into a Rack
1. Remove the four rubber feet by removing four
screws from the bottom of the CPU Switch Unit.
2. Install the CPU Switch Unit into the rack securing it
with four screws (not included).
Cautions:
• Do not block the ventilation opening or slots on the
cover to prevent the appliance from overheating.
Always keep the temperature in the rack within 45°C
(113°F).
• Secure the rear of the appliance to the rack by
using the additional mounting brackets (procured
locally) if the rack is subject to vibration.

■Operations
Power on CPU Switch Unit first. The power switch of
this unit is located underneath the front panel.
Remove the front panel by removing the 4 screws
on the panel.
The CPU Switch Unit has a default setting: the A
CPU is the active CPU.
After powering on this unit, the "A" button will be on
and the "B" button will be off automatically. It will
also light the "AUTO" button to indicate that the auto-
switching mode is selected.
Secondly, power on A CPU and B CPU. While the
CPUs are booting, the diagnostic indicators on the
front panel will be turned on. At this moment, A CPU
is selected as the active CPU and B CPU is held at
the standby mode.
If an error occurs in A CPU, the diagnostic indica-
tors will turn off and A CPU will be reset. Then the
"A" button will be off.
On the other hand, the CPU Switch Unit will switch,
the B CPU as the active CPU.
The "B" button will be on and the "AUTO" button will
be blinking. This blinking means that a CPU switch
has occurred in the past days.
In the blinking mode, even if B CPU is corrupted
and A CPU is good condition, this unit will judge to
switch the active CPU from B CPU to A CPU. After
checking the reason of the CPU switch and remove
problems, please change the flashing mode to nor-
mal automatic mode by pressing the "AUTO" button.
The manner of changing B to A is same as A to B.
Also this unit can be operated manually. Pull up the
protection cover of the "AUTO" button and press
"AUTO", it’s LED will go off and it will change to
manual mode. In manual mode, it is possible to
select the active CPU manually by pressing the "A"
button or "B" button. Also it is easy to change to the
automatic mode by pressing the "AUTO" button in
the LED on status.
Finally this unit has individual reset buttons for each
CPU. By pressing the "A RESET" button, you can
reset the A CPU, and by pressing "B RESET" button
you can reset B CPU.
The "AUTO", "A", "B", "A RESET" and "B RESET" but-
tons are protected with a see-through cover.
